Introduction Microsatellite instability (MSI) is an important pathway in colorectal carcinoma (CRC) pathogenesis. MSI occurs due to mutations mismatch repair (MMR) genes that include MutL protein homolog 1 (MLH1), postmeiotic segregation increased 2 (PMS2), MutS (MSH2), and 6 (MSH6). CRC with termed MMR deficient (dMMR) CRC. Conversely, intact called microsatellite stable (MSS) or proficient (pMMR). In this study, we compared the clinicopathological features of dMMR pMMR Methods It was a...
